Code OK on dev server, not on webserver

Anon

Hey, everyone.

Here's a bit of code that is supposed to check a referring page for  and  tags and return all the content so I can display it as a printer-friendly document, w/o any graphics etc.

It's called just by linking to it. Ignore the HTML, that's just to make it look somewhat pretty.

Wierd thing: works on my dev server and not on my webserver. Both run PHP 4.

Any explanations?

<HEAD>
<title>Premier :: Achievement :: Effectiveness</title>

<STYLE TYPE="TEXT/CSS">

It would be easier to advise if you were more specific on what actually happens. Do you get any output to the browser at all, just not the right stuff?

Well, on my dev server it works great, returns the title, the URL, the content, and displays them properly.

On my production server, it returns the URL, and of course the built-in HTML of the print.php page itself, but NOT the content that the ereg statements are supposed to grab from between the  and  tags.
